Question

identify how each birth defect develops. * genetic environmental combination cerebral palsy cleft lip/palate congenital heart defects down syndrome fetal alcohol syndrome neural tube defects (i.e. spina bifida) std/sti related defects

Explanation:

Cerebral Palsy can be due to a combination of genetic and environmental factors during pregnancy or birth. Cleft Lip/Palate often has a genetic - environmental combination cause. Congenital heart defects can be due to both genetic and environmental factors. Down Syndrome is a genetic disorder caused by an extra copy of chromosome 21. Fetal Alcohol Syndrome is caused by maternal alcohol consumption during pregnancy (environmental). Neural tube defects like Spina bifida can be due to a combination of genetic and environmental factors (e.g., folic acid deficiency). STD/STI - related defects are caused by the mother having an infection during pregnancy (environmental).

Answer:

Cerebral Palsy: Combination
Cleft Lip/Palate: Combination
Congenital heart defects: Combination
Down Syndrome: Genetic
Fetal Alcohol Syndrome: Environmental
Neural tube defects (i.e. Spina bifida): Combination
STD/STI related defects: Environmental
